Title: Ventilating device employing solar cell
Inventor: NISHIHARA TAKASHI
IPC: F24F7/007
Filed: 1985-06-13
Abstract: PURPOSE:To enable to perform usual ventilation during some period even after lowering of the intensity of illumination of the collecting window of a solar cell, by a method wherein the output voltage of a storage battery charged with an electromotive force produced by the solar cell is fed to a fan motor through a voltage-detecting control means. CONSTITUTION:Since the electromotive force of a solar cell 1 under sunshine is equivalent to or higher than the voltage of a storage battery 3, the storage battery 3 is charged in a condition that a non-return means 2 is rendered inoperative. Meanwhile, the electromotive force of the solar cell 1 is lowered under cloudy weather or sunset, and the non-return means 2 is worked to disconnect the circuits of the storage battery 3 and the solar cell 1. When the output voltage level of the storage battery 3 exceeds the upper limit of a previously set value through the action of a voltage-detecting control means 4, a fan motor 5 is run, and when it is reduced to lower than the lower limit of the set value resulting from a following discharge, the fan motor is stopped. This enables continuance of ventilation during a specified time even after the intensity of illumination of the collecting window of the solar cell 1 is lowered.

Title: Voltage controlled oscillating circuit
Inventor: SUZUKI KOUZOU
IPC: H03K3/0231
Filed: 1982-07-23
Abstract: PURPOSE:To enable a titled circuit to be operated at a low volage supply, by taking a reference voltage of a comparator as an output power supply and forming independently a constant current source of a comparator and a charging source from other power supplies. CONSTITUTION:When a potential of a time constant circuit 5 is larger than a reference potential (b), a transistor(TR)Q2 turns on to decrease the reference potential (b) and a TRQ5 is turned off to stop charging and to start discharging. When a potential (a) is smaller thanthe reference potential (b), the TRQ2 turns off to restore the reference potential (b) and to restart charging. As a result, an oscillating signal having an amplitude determined with a reference power supply VS and resistor groups R1-R3 is outputted to an output terminal 1. Further, since there is a volage drop portion due to a TRQ4 only in the charging power supply 4, a voltage amplitude of a power supply VCC is utilized effectively. Thus, the amplitude output determined with the reference power supply VS and a resistor group 6 is obtained at a low voltage supply.

Title: Electric dust collector
Inventor: YADA KATSUTOSHI
IPC: B03C3/68
Filed: 1979-10-05
Abstract: PURPOSE: To prevent an air preheater from attachment of dust and corrosion along with a higher denitration performance by controlling soots density at the exhaust gas outlet above a specified lower limit based on the density detection signal from a soots density measuring gage provided at the outlet of a dust collector.  
     CONSTITUTION: A soots density measuring gage 7 is mounted at an exhaust gas outlet of a high temperature electric dust collector 2 connected to a coal-fired boiler 1. The gage 7 is connected to a dust collection efficiency regulator 8 to be controlled within the range of 100W300mg/Nm 3  so that the soots density is above a specified minimum value at the exhaust gas outlet of the dust collector 2. As a result, when the exhaust gas following dust collection is passed through a denitration unit 3 to remove NO x , amount of dust attached to a denitration catalyst is relatively limited. Combined with adhesion of acid ammonia sulfate generated from an air preheater to dusts, this prevents clogging or corrosion of the elements.

Title: Piston ring
Inventor: KUMAI TERUO
IPC: F02F5/00
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of sealability to resin piston ring which is caused by combustion pressure. SOLUTION: In an outer ring 2, a tip end surface 10a of a lower projection streak 10 is less than a tip end surface 8a of an upper projection streak 8 in width. More deteriorative pressure is applied to an inner peripheral surface 20a of a cylinder 20 comparing with that of the tip end surface 10a of the lower projection streak 10. The tip end surface 8a of the upper projection streak 8 which substantially directly receives combustion pressure has large width and shows stable stance for a long time. Twisting of the outer ring 2 caused by combustion pressure is thus effectively prevented. Since the pressure on the tip end surface 10a of the lower projection streak 10 is higher than that on the tip end surface 8a of the upper projection streak 8, adhesiveness to the inner peripheral surface 20a of the cylinder 20 is improved.  Engine oil is prevented from leaking from the side of a crank case to a combustion chamber side. Deterioration of sealability is thus sufficiently prevented.
